CAR-COUPLING.-

SPEGIFIGATION forming part of Letters Patent No. 512,630, dated January9, 1894. Application filed November 4, 1893- Serial No. 490,055. (Nomodel.)

To all whom it may concern.

Be it known that I, JOHN O. TAYLOR, of Findlay, in the county of Hancockand State of Ohio, have invented certain new and useful Improvements inOar-Couplings; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in car couplings, and it consistsin the novel features of construction hereinafter referred to andespecially pointed out in the claims.

. The object of my invention is to'provide a coupler of the J anney typewith an improved latch for securing its swinging j aw in position.

Referring to the accompanying drawings: Figure 1, is a perspective Viewof a coupler provided with my improved latch, the jaw being releasedtherefrom. Fig. 2, is a horizontal cross sectional view, the latch andthe jaw being in engagement. Fig. 3, is a similar view with the latchand jaw removed.

Fig. 4, is a perspective view of the latch.

A designates the recessed drawhead of ordinary construction havingpivotally secured to one side of its outer end the swingingjaw B.Projecting therefrom is tongue 0, which, when turned backward,is adaptedto engage arm D extending from rod E, thereby turning the said armbackward into the head and so rotating the rod as to bring arm Fdirectly over vertical 'openingG in the lower wall of the drawhead. Thisopening communicates with a segmental groove in the said wall andadapted to move in said groove H is pin I which depends from arm F. Whentherefore the last named arm has been turned over said passage G and thepin E together with arms D and F will drop owing to the engagement ofpin 1 with passage G. Thus it will be seen that tongue 0 is securelylocked by the latch and there held in a permanent position. The jaw isthus prevented from swinging outward until the whole latch mechanism iselevated so as to free pin I from opening G. The latch will then turnbackward as shown in Fig. 1 and release the jaw thus effecting theuncoupling operation. For elevating the latch I provide a rod J whichextends upward on the car end and through a bracket K secured to thecar. The upper edge of this bracket is inclined as shown and overhangingthe same is lip J carried by rod J which when at the bottom of theinclined bracket surface permits the latch to fall to a locking positionbut which when turned to the opposite and highest part of the bracketelevates the rod and latch as will be readily understood. By means ofthis construction the lateral movement of the latch as well as itsvertical play may be controlled from the cartop. The latch may also beelevated and rotated by the longitudinally movable crank shaft L securedto the car end and carrying pin L which plays in slot M of armMextending laterally from rod J. The said pin L is carried by a collar Nwhich is loose on the crank of shaft L, and by this arrangement allbinding of the connected parts is avoided while being operated.

Having thus described .my invention, what I claim, and desire to secureby Letters Patent, is-- r 1. The combination with adrawhead,a jawpivoted between its ends thereto, a revoluble latch adapted to hold theinner end of the jaw, and a pin on said latch adapted to engagea passagein the drawhead, substantially as shown and described.

2. The combination of a drawhead, a jaw pivoted between its endsthereto, a vertically movable and revoluble latch, and a pin carried bythe latch which is adapted to engage the opening in the drawhead therebyholding the jaw in a locked position, substantially as shown anddescribed.

3. The combination of a recessed drawhead having a segmental groove inits under wall, a jaw pivoted between its ends to the draw head,arevoluble latch in the drawhead, an arm projected therefrom which isadapted to engage the inner end of the jaw, and a pin extending fromsaid arm which is adapted to move in said segmental groove and engagepositively a vertical passage in the said wall, substantially as shownand described.

4;. The combination of a drawhead, a swinging jaw therein, a verticallymovable and revoluble latch, a rod extending upward therefrom, aprojection on the upper end of,the rod, and a bracket secured to the carend which is formed with an inclined top surface which plays in the slotof the arm, substan- IO over which the said projection is adapted totially as shown and described.
